PC Crane and PC Bellamy give chase to a couple of hooligans in a car. When they pass the bus stop in Aidensfield Paul Dibley is teased by a school friend and runs right smack into the side of Bellamy's passing police car. He suffers only a broken leg and some bruises, but his father Don wants PC Bellamy prosecuted. Paul's sister Tracey has just started as a maid at Ashfordly Hall when it is discovered that she is pregnant. Understandably she is afraid to tell her father especially since the father of the baby is her cousin Lenny. To make things worse Tracey gets a crush on PC Crane and names him as the father instead when her parents find out about her pregnancy.
